I could see it work with Shatter Defenses... but archery feats + focus + Dazzling + Shatter + Arcane Strike - its a lot of feats for a mage that don't support his focus.
Meanwhile end game I tend to blast in a lot of encounters anyway - making those archery feats wasted.
The vast majority of the game is spent in the non endgame. It is indeed a challenge getting all her extra attacks to land as an archer, but those kind of challenges are what make the game fun. If I can get the crappy summons in this game to connect, I can do it with Octavia.
Here’s a hint: if she’s getting sneak dice, she’s flanking, so Outflank and Freebooter’s Bond work. Also Inspire Courage and all the debuffs from the original comment about building an enchantment/illusion sorc. Of course then you also get to use some of the busted bows in this game. Arcane Strike is unnecessary as it’s only damage, not to hit, and not much damage.
I start her out with all four rogue levels to get my BAB money back I already paid for and I’m a sucker for uncanny dodge and debilitating attack but that’s not strictly necessary.
